QualitySettings

Inheritance: java.lang.Object

public final class QualitySettings

QualitySettings allows to configure recognition quality and speed manually. You can quickly set up QualitySettings with embedded presets: HighPerformance, NormalQuality, HighQuality, MaxQuality or you can manually configure separate options. Default value of QualitySettings is NormalQuality.


This sample shows how to use QualitySettings with BarCodeReader
 
 //set HighPerformance recogition mode
 BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighQuality recognition mode
 BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighQuality());
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighPerformance recogition mode for low sized barcodes
 BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     reader.getQualitySettings().setXDimension(XDimensionMode.SMALL);
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }
 //set HighPerformance recogition mode for low quality barcodes
 BarCodeReader reader = new BarCodeReader("c:\\test.png", DecodeType.CODE_39_EXTENDED, DecodeType.CODE_128);
 {
     reader.setQualitySettings(QualitySettings.getHighPerformance());
     reader.getQualitySettings().setBarcodeQuality(BarcodeQualityMode.LOW);
     for(BarCodeResult result : reader.readBarCodes())
         System.out.println(result.getCodeText());
 }

applyAll(QualitySettings Src)

public void applyAll(QualitySettings Src)

Function apply all values from Src setting to this

Parameters:

ParameterTypeDescription
SrcQualitySettingssource settings

equals(Object arg0)

public boolean equals(Object arg0)

Parameters:

ParameterTypeDescription
arg0java.lang.Object

Returns: boolean

getAllowIncorrectBarcodes()

public boolean getAllowIncorrectBarcodes()

Allows engine to recognize barcodes which has incorrect checksumm or incorrect values. Mode can be used to recognize damaged barcodes with incorrect text.

Value: Allows engine to recognize incorrect barcodes.

Returns: boolean

getBarcodeQuality()

public BarcodeQualityMode getBarcodeQuality()

Mode which enables methods to recognize barcode elements with the selected quality. Barcode element with lower quality requires more hard methods which slows the recognition.

Value: Mode which enables methods to recognize barcode elements with the selected quality.

Returns: BarcodeQualityMode

getClass()

public final native Class<?> getClass()

Returns: java.lang.Class

getComplexBackground()

public ComplexBackgroundMode getComplexBackground()

Mode which enables or disables additional recognition of color barcodes on color images.

Value: Additional recognition of color barcodes on color images.

Returns: ComplexBackgroundMode

getDeconvolution()

public DeconvolutionMode getDeconvolution()

Deconvolution (image restorations) mode which defines level of image degradation. Originally deconvolution is a function which can restore image degraded (convoluted) by any natural function like blur, during obtaining image by camera. Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology.

Value: Deconvolution mode which defines level of image degradation.

Returns: DeconvolutionMode

getHighPerformance()

public static QualitySettings getHighPerformance()

HighPerformance recognition quality preset. High quality barcodes are recognized well in this mode.
